About the demand data...
National Grid see solar PV generation as a reduction in demand, this means that the metered 'Demand outturn' represents the 'True' electricity demand minus the generation from Solar and small-scale unmetered Wind. Similarly, the forecasted demand is a forecast of the demand outturn i.e. without solar generation.
Here we present both the unaltered 'Demand outturn' and 'Demand Forecast', as well as the 'True Demand' which is calculated as the 'Demand outturn' plus the solar PV generation.
(N.B. We do NOT currently add NG's estimate of unmetered wind generation in our calculation of 'True Demand', but this is something we're working on including.)
